Differences Between Self-Assessment and External Rating of Voice With Regard to Sex Characteristics, Age, and Attractiveness

Although the objective parameters of age and gender identification could be rated with a high degree of accuracy, subjective parameters showed significant differences between self-assessment and external rating, in particular in rating women's voices. Taking these findings into account in treatments for modifying voice could impede successful interventions. As one consequence, we recommend summarizing target agreements in detail before the treatment.
